Enclosure of grass lands
-
Elimination of the grazing factor, which is directly responsible for the deterioration of the grasslands, induces a progressive succession. It can therefore serve as a very effective method of improving degraded grasslands.
-
Closure for a few years will be effective when the reminants of better species are still scattered in the area, to serve as seed sources. 4 or 5 years of closure may be necessary but if the deterioration has already proceeded to the 'poor' condition when only annual species of grasses are left to grow, than the regeneration even under closure may be much slower.
